Peer Support Program in Cancer Patients Elkar Laguntza

The general aim of the present research will be to evaluate the effectiveness of a peer social support intervention in cancer patients at the Onkologikoa Foundation of Guipuzcoa. Specifically, the immediate and long-term effect that such intervention will have on symptoms of psychological distress, quality of life, coping strategy, perception of social support, perception of the disease and emotional regulation will be evaluated. As a secondary aim of this study, we intend to evaluate the immediate and long-term effect of the peer social support intervention on the immune system (through the determination of the levels of cytokines IL-1β, IL-2, IL-6, IL-8, IL-10, IFN-γ and TNF-α), on the monoaminergic system (through the determination of plasma levels of serotonin, tyrosine, phenylalanine, tryptophan, quinurenine, quinurenic acid and 3-HK), on the HPA axis (through the measurement of the diurnal cycle of cortisol), and on sex hormones (through the measurement of estradiol and testosterone levels), systems that have been related both to the development of anxious-depressive symptoms and to the development, progression and recurrence of cancer. In addition, it will be studied at what time the application of the program is most effective, being applied in newly diagnosed patients (experimental group 1) and in patients who have just finished medical treatment (experimental group 2).
